Republic silvered-bronze Pattern Peso 1888 MS61 NGC, Uncertain mint, likely Buenos Aires, KM-unl. An exceedingly rare off-metal strike of an already rare pattern issue, this piece is listed in KM in silver, bronze, and aluminum, but not this silvered-bronze variety. Accordingly, the only example which NGC has certified. Deeply toned, with some original luster still remaining. A stunning and wondrous rarity.
